Name Signs, Keychains and QR Codes: The Best Free Generators

Text is the easiest way to make a print personal. A name on a desk plate, a keychain for every child in the class, a QR code for the guest Wi-Fi. These are also the prints people ask makers for most, so a good set of generators pays off quickly.

Quick answer

• Best sign maker: Make My Sign (MakerLab). Free browser editor for name plates, badges and signs, exports multicolour 3MF.

Signs and name plates

Make My Sign is Bambu Lab’s own sign editor inside MakerLab. You type your text, pick a shape and colours, and download a 3MF with the colours already assigned. It is free with a MakerWorld account.

For a curved desk name plate, the Sweeping 2-Line Name Plate is one of the most customised models on MakerWorld. Text2STL is the go-to web tool when you just want letters: pick from more than 1,000 Google Fonts, choose plain, plate, engraved or standing text, and download an STL.

House numbers have their own House / Office Number Plate Generator with six styles in two colours. For accessibility signs, BrailleGen turns text into Grade 1 or Grade 2 braille tiles.

Keychains and tags

The Custom Name Keychain Generator makes layered name keychains in any Google Font, including non-Latin scripts, or from your own SVG. The Name Keychain Generator [NO AMS] is built for single-nozzle printers: its bubble-outline design gives two colours with one filament swap.

To turn a picture or logo into a keychain, use Image to Keychain (MakerLab). For pets, the PETTAG V.2 puts the name on the front and phone numbers on the back.

QR codes, Spotify codes and NFC

The Customizable Parametric QR Code Generator on MakerWorld handles links, Wi-Fi logins, phone numbers and contact cards. Without an account, QRCode2STL is an open-source web app that also does Spotify codes and NFC-ready tags.

For a song on a keychain, the Customizable Spotify Keychain / Tag makes a scannable Spotify code, with an optional slot for the cover art.

Tips for crisp text and codes

• Keep letters at least 1 mm thick and strokes wider than your nozzle (0.4 mm or more).
• Change colour at the right layer. Most generators tell you the height; otherwise use your slicer’s layer preview.
• Print codes flat on the bed, face up, and test with your phone before you print a batch.
• Add an NFC tag under a QR plate so phones can tap as well as scan.

Frequently asked questions

How do I print a two-colour name keychain without a multicolour printer?

Add a pause or filament change in your slicer at the layer where the letters start. When the printer stops, swap the filament and resume. Generators such as the Name Keychain Generator [NO AMS] are designed for exactly this.

Will a 3D printed QR code scan?

Yes, if the contrast is strong and the modules are crisp. Print black on white (or the other way round), keep the code at least 4 to 5 cm wide, and use a 0.4 mm nozzle or smaller.

Can I sell keychains I make with these generators?

It depends on the licence. Many MakerWorld customizers are for personal use only, and some designers sell a commercial membership. Web tools such as Vextrude say you may use the models commercially. Check each listing.

What is the best filament for keychains?

PLA works for most keychains. Silk PLA gives a shiny look, and PETG or TPU hold up better on keys that live in a pocket.
